This paper presents a low loss and high suppression monolithic inverse wavelet transform processor (MIWTP) using surface acoustic wave (SAW) devices. New functions for achieving the MIWTP have been derived. Its structure combines a withdrawal weighted single phase unidirectional transducer (SPUDT) with an apodized SPUDT. The experimental device is achieved with the aluminum electrode and the 128 degree rotated Y-cut lithium niobate (LiNbO₃) substrate. Measured results demonstrate the center frequency 68.1 MHz, the minimum insertion loss (IL) 5.4 dB, the 3-dB fractional bandwidth 1.3% and the sidelobe suppression over 40 dB.
